Just really don't see the worth in trying it period. There are enough privacy focused free search engines that get me all the answers i need from a search already. I have no reason to want to invest more into it. And i think general public would see it the same way.
Kagi based on its features doesn't have a good enough value proposition for me to even want to try it out cause really what more are they offering?
it may be a good value proposition for people who lives revolve around searches and research but it ain't a need I have and unless ypur part of that group idk why youd want to pay for it.
And don't said ads. They are honestly laughable easy to get around still or even ignore.
Maybe if you read what i said you'll figure it out.
